This video doesn't just deserve an A+, it deserves a diploma straight into the hands of its creator. Screw the rest of this dude's curriculum -- this wins college.
One of the best things about kids is that they have no pre-conceived notions about certain things like music. They know nothing about the sub-culture of each genre and the politics within it. Their minds fall into the realm of "I may not know art, but I know what I like." In this case, art is brutal death metal.
Ever wonder how vocalists in death metal bands get their voices ready? Well, until I saw this video, I didn't either. Is it just me, or does this guy remind you of Nigel Tuffnel of Spinal Tap a little bit?
